This 1970’s ROYCE DUAL TIME vintage watch is pretty cool. The 27x36mm. mm. steel case houses two movements, so you can have two separate watches displaying two different time zones. Both manual winding movements are accurate after a recent cleaning. The silver dials cannot be appreciated until you see them in person, as both original dials alternate from light to darker silver when seen in a different position. Any age spots on the right dial are barely visible with the naked eye. These dials really catch and reflect the light-awesome.
